The world's only carbon-negative power source (pictures)
BERKELEY, Calif. -- All Power Labs, a startup in this city across the Bay from San Francisco, makes what it says is the world's only carbon-negative power system.
Its PowerPallet systems come in 10- and 20-kilowatt configurations and produce a fuel using a process called gasification that will work in most engines by feeding in dense biomass. The company says that its system can produce power for about $1.50 per watt, and is being used in many developing nations to produce power for about a third of the cost of existing systems. Most buyers purchase the $27,000 20kW system.
In addition to producing carbon-neutral electricity, the machines also produce a carbon-rich charcoal that can be used as a very effective fertilizer. Because it pulls more carbon out of the sky than it puts back in, the company says the system is carbon-negative.
